Thank you for your enquiry.
The Templates solution obtains information about the local and shared folders from an INI file in the workstation’s Windows folder.
There might be some reason why, for user B, Templates is failing to read this INI file correctly. We will be sending a test applet to your email address for you to run in order to see what is being loaded from the INI file.
By the way, I notice that your installed version of Formativ is 126.96.36.199. You may wish to consider doing a free upgrade to version 188.8.131.52, which adds a number of improvements.
